CONTRACTOR QUESTIONS

Questions, Answers, ClariÞcations, and Revisions: The following are based on questions received after the Invitation to Bid was published on April 17, 2025.

1. Question: RFP Process – Question - In the pre-bid agenda handout it states this RFP procedure is on QuestCDN and the City website. I’m not Þnding it anywhere. Please provide direct access to this process. I am very skeptical of RFP unless I see the criteria. I’m also skeptical of the people reviewing and their qualiÞcations. If there is a prequaliÞcation process for bidding then at least contractors know before they waste a bunch of time preparing a bid for a project that they have no chance of getting.

a. The City’s Website (Home screen tab) and the Quest CDN site have the RFP in the "View Bid Documents" section.

b. RFP criteria and selection rating criteria are provided in the RFP document.

c. The City will be the primary reviewer of the Proposal. The engineering team will perform technical review of the proposal details and contact references provided for use by the city rating team. All ‘ratings’ will be performed by the city selected review panel.

2. Question: Why is the design and engineering on the contractor? Why isn’t Windsor or North Coast providing a design and engineering? This doesn’t make any sense to me. If

Manzanita Classic Street Connection Project – Addendum #2 Page 3 of 17 contractor does the design and engineering then that means that Windsor and North Coast have no say on inspection or installation of the wall. Having multiple engineers on a project is redundant, wasteful, and destine for conflict.

a. The retaining wall design is the contractor’s responsibility as to not limit the type of wall the contractor may choose or has experience in constructing.

This will allow the contractor to bid on the retaining wall type that they are most comfortable and most experienced with and to be able to provide the best possible price. Windsor, with input from Pali (Geotech engineer), developed a preliminary design for a type of wall (gravity block wall). The geotech also reviewed the use of an MSE wall as a potential design. The Geotech report provides recommendations that will be implemented in the submittal review, and the Contractor should review this information for obtaining input from their wall supplier in designing the wall and providing prices.

b. Stamped & signed wall design and construction plans are not required for the bid/RFP submittal. Stamped & signed retaining wall plans will only be required as a submittal by the selected contractor.

c. The City Team will still have jurisdiction regarding submittal review and inspection of the wall installation.

3. Question: What coordination with developer is expected? Isn’t all of the work as part of this project in the public right-of-way? I don’t see where this project crosses into a TCE or onto the developers property. Am I missing something?

a. There is a 15' temporary easement west of Classic south of Dorcas (Sheet C600). This property may be developed/constructed during the same time as the city project. If wall construction is coordinated with the adjacent development, it will beneÞt the Classic Street project; this is informational only, and the contractor should take whatever steps he feels are prudent in preparing his bid.

4. Question: Storm drain mainline right adjacent to the wall. This seems like such a bad idea. Any maintenance ever on this storm line will compromise the wall. If the wall is designed with any tie-back fabric then this pipe system will be in conflict. Why can’t the storm main be installed in the middle of the road away from the wall? Run laterals to the catch basins.

a. Storm system was designed along the edge of pavement to reduce cost and maintenance by reducing pipe (leader lines) and structures needed for the storm sewer.

b. Storm sewer along the roadway center line may or may not reduce the cost of the wall construction but would increase the cost of the storm sewer. If the contractor feels that this is a beneÞt, they can propose a value-engineered alternative.

Manzanita Classic Street Connection Project – Addendum #2 Page 4 of 17

5. Question: Is it really necessary to do trenchless HPDE for watermain? This will be expensive for this short run. The road will have to be core drilled anyway to locate existing utilities.

a. Yes, this was a direct city requirement to not open cut trench the watermain through Necarney City County Road.

6. Question: The list of bid items includes Bid item 19 “Retaining Walls” and gives an average height of 22’ in the bid item. When I review the wall proÞle, it appears the walls will be far less than 22’ tall on average. See plan sheet C-600. Would the City please conÞrm veracity of “Avg Height = 22’?

a. The 22' average height was based on the initial engineered design, measured from the bottom of a footing to the top of the wall. The wall proÞles will be (Sheet C600) the controlling design parameter. Additional plan information is provided with this addendum. AutoCAD developed elevation and contour information will be available on the QuestCDN site attached to Addendum 2 information.

NOTE: The Þnal wall height should be determined by the contractors' deferred design based on the recommendations in the geotechnical report.

b. The wall proÞles in the plan sheets are estimated based on Pali’s Geotech report. They show existing grade and proposed wall heights based on theinital wall selection and recommendations of the geotech.

7. Question: The proposal quantity for item #14 General Excavation is 560 cy. The notes on the civil plans state that there is 1,286 cy of cut and 1635 cy of Þll. Please clarify.

a. The volumes estimated for the Bid Item 14 - 560 CY have been revised to approximately 1320 CY of total excavation and 3160 CY of embankment Þll required (neat line calculations) for the entire project, resulting in approximately 1840 CY net Þll. This estimate does not include volumes based on the wall design chosen. For bidding purposes, the contractor should use their individual design to determine the Þnal quantities. Updates for the notes on the civil plan sheets have been provided.

8. Question: The proposal item #16 Borrow Excavation for 760 tons is apparently to come from off-site to make the necessary Þlls in the roadway section. Since there is expected to be surplus excavation from the retaining wall scope, is there any reason that the surplus structure excavation from the retaining wall couldn't be used to build the Þlls? If so, would the city be open to paying the item #16 work by an agreed conversion from cubic yards to tons?

a. In most cases, the excavated material from the retaining wall may be suitable for project Þll. This may be paid by cubic yards (or by ton) with an appropriate conversion factor of ~1.4 ton per cubic yard (truck measure) to be negotiated with the city. The contractor should bid or prepare to provide a credit back to the City.

Manzanita Classic Street Connection Project – Addendum #2 Page 5 of 17

9. Question: The proposal quantity for item #17 Base Course Aggregate is 1,693 cy. A take off yields approximately 20% more volume. Can you conÞrm the quantity?

a. The base course aggregate total volume has been revised to 2,000 CY.

ConÞne activities and operations to the area immediately adjacent to the Right-of-Way line and within the highway Right-of-Way. Arrange for permits required from adjacent property owners to perform the Work.

304.4.1.A Schedule the installation of fencing or provide temporary fencing or other adequate means to prevent livestock from entering the Project Right-of-Way, easements and/or adjoining properties according to 00170.92.

304.4.1.B Lines, Grades, and Preparation Work - Unless otherwise directed, set fences so the fence fabric and wires are visually straight, plumb and consistent. on Right-of-Way lines or Agency property lines, with posts set on Agency property. If directed, center concrete footings and fence posts 1 foot from the Right-of-Way or property line on Agency property.

304.4.1.C Clear, grub and prepare the fence line area. Remove all shrubs, brush, snags, downed timber, float Rock, and other obstacles, including trees up to 6 inches in diameter which interfere with fence construction. If directed, preserve trees and geographic features on fence lines by varying the fence alignment to miss them.

304.4.1.D Fill or excavate ground surface irregularities which interfere with maintaining speciÞed clearance above ground surface of the bottom wire of the fence. Limit the width as necessary to provide a clear way for the fence.

304.4.1.E Excavate for concrete footings to reasonably Neat Lines, but not less than the speciÞed dimensions in Soil, or not less than 18 inches deep in Rock. Prevent disturbance of original ground at the sides and bottom of the excavation. Installation shall be on the top of the retaining wall. Fence post bases shall be constructed as shown in the Contract Plans – C502 Chain Link Fence Detail, using a plate and anchor bolt installation. Leveling nuts shall be added below the plates in order to level and plumb the installation. Following Þnal leveling the Contractor shall grout the space between the wall and the base plate.

304.4.1.F Clear and grade gate openings to permit the gate to swing in a horizontal plane according to 01050.48.

304.4.1.G Dispose of materials removed under these provisions, including excess excavation, in a satisfactory manner.

304.4.2 Optional Posts - Use steel or wood posts in barbed, or barbed and woven wire fence construction according to one of the following options, and once an option has been selected, use that option throughout the Project:

Steel posts shall be installed entirely in all types of fence.

304.4.3 Installing Posts and Braces:

304.4.3.A General - Set all metal end posts, intermediate end posts, corner posts, gate posts, and chain link fence posts in concrete footings or as described in Section 3.04.4.1E above. Set all other posts Þrmly in the ground or in concrete footings as the Contractor elects.

304.4.3.A.1 Set posts to the depths shown. Reasonable variation in depths will be allowed and posts may be appropriately shortened or left slightly high, as approved by the Engineer, to:

Avoid unnecessary penetration or excavation in Rock or other unusually Þrm material.

Obtain desired grades along the fence.

Manzanita Classic Street Connection Project – Addendum #2 Page 13 of 17

304.4.3.A.2 Set all posts vertical, except on curved alignment set posts slightly off vertical, as directed, to offset the pull of the fence fabric and wires.

304.4.3.A.3 For bridge protective fence and wall mounted only, set all metal end posts, intermediate end posts, and chain link fence posts as shown.

(1) Driven Posts - Posts that are set by driving shall be free of damage when set. Remove and replace any driven posts that are split, twisted, or bent, or have badly misshapen tops.

Dug Holes - Where Rock is encountered, set the posts to depths of not less than 18 inches and backÞll with Þne Granular Material. Do not exceed the post height shown by more than 3 inches. When posts are set in dug holes, backÞll in 6-inch layers with each layer separately and thoroughly tamped and compacted.

(3) Concrete Footings - Dimensions of footings shall not be less than shown and shall Þll the excavated areas. Place the concrete with contact against Þrm Soil at the sides and bottom and tamp around the posts and brace ends after the posts and braces have been brought to and Þrmly held in proper position. Strike off, slope or crown and smooth the surface of the concrete at the ground level to shed water. Allow to cure for at least 5 Calendar Days before subjecting the posts and braces to strain.

304.4.3.B End Posts - Set end posts:

At the beginning and end of new fence construction that is not terminating at gate posts.

At the end of the intersecting line of existing fences just outside the line of the new fence.

304.4.3.C Intermediate End Posts - Set intermediate end posts in the line of the new fence:

At each summit and at each valley in the grade of the fence where the algebraic difference in the grades of adjoining panels of fence exceeds 30 percent.

At other points located along the new fence line to break the fence construction into approximately equal runs not exceeding the applicable lengths of runs shown.

304.4.3.D Corner Posts - Set corner posts as follows:

Chain Link Fences - At angle points in fence alignment where the alignment of adjoining panels of fence changes direction by 20 degrees or more.

304.4.3.E Line Posts - Set line posts along the line of fence, between end, intermediate end, corner, and gate posts, and at the spacings shown. Line posts may be set at spacings not exceeding 25 percent greater than speciÞed or at closer spacings if approved. Set a line post in the new fence line at a point in alignment with each intersecting fence line approximately 1 foot from the end post of the intersecting fence line. It is intended that the actual number of line posts will average to the number required for normal spacing.

304.4.3.F Braces - Construct braces before placing of fence fabric and wires on the posts.

304.4.3.F.1 Metal Braces - Provide corner posts and intermediate end posts with two braces, one each direction from the post in the main fence lines.

SECTION 305 – METAL GUARDRAIL

The following information shall supplement existing Oregon Department of Transportation Standard SpeciÞcations for Construction. These provisions shall take precedence over any conflicting speciÞcations.

305.00 Scope - This Work consists of constructing metal guardrail to the lines and grades shown or established and includes the assembly and erection of all components, parts and Materials complete at the locations shown or directed. Metal guardrail and metal Median barrier will be referred to in this Section as "guardrail". The types of guardrail will be shown. Work shall be performed in accordance with these special provisions and Section 00810 of the current release of the Oregon Department of Transportation Standard SpeciÞcations.

305.11 Posts - Posts, except as speciÞed for use on Bridges or otherwise shown or directed, may be of steel or wood, as the Contractor elects. Once a type has been selected, use it throughout the continuous run of guardrail except in the transitions and terminals.

305.13 Guardrail Anchors - Furnish steel guardrail anchors according to Section 02820 and as called out in the plans. No guardrail anchor cable assembly per Project for testing according to AASHTO M 30 will be required.

Construction

305.40 Timing and Coordination of Work - Time and coordinate construction of guardrail to hold disturbance of Bases, Surfacings and Pavements to a minimum. Place all metal Median barrier Materials in continuous runs. Do not leave posts installed for guardrail exposed to trafÞc for more than 24 hours before installing the rail members, rail end pieces and anchors and tightening all bolts, except replacement rail shall be installed according to 00310.40(a).

305.42 Installation of Posts and Anchors - Place posts and anchors as shown. If directed, install 8 foot guardrail posts. Drive posts in place. If posts are driven through the Bases, Surfacings, Pavement or other utilities repair all damage as directed. Remove and replace posts, anchors or other components damaged during installation with sound components. Firmly set all posts at proper line, grade and spacing within a tolerance of 1/2 inch. Rigidly attach anchors, terminals and connections to other Structures as shown.

Guardrail posts shall be 7’-6” in length.

Anchor posts shall be Type 5 installations as shown in the plans (C500).

300.43 Erection of Rails and Other Components - Normally, all fabrication of metal beam rail members and other components shall be done in the shop or by the manufacturer. Limit Þeld cutting, drilling and other Þeld fabrication to the minimum and perform in a manner that will not impair the appearance or structural quality of the material. Burning new holes in metal beam rail members is not allowed.

Restore to speciÞed condition, surface Þnishes and protections that are damaged before or during erection. Repair the cut ends of galvanized bolts, rail elements and back-up plates, and any holes drilled or punched after galvanizing according to ASTM A780. Minimum zinc content for Method A2 is 94 percent on the dry Þlm.

Toe nail blocks to post with two 16d, galvanized, flat head nails to prevent rotation.

Draw tight all bolts. Bolts shall be of sufÞcient length to extend slightly beyond the nuts
